[can't stop spinning]

Here's the problem with driving around with the tailgate open. About 3-5 times a year, I'm planning on going camping/quading. My travel trailer is light enough that I'm not too worried about being overloaded. However, with the hitch I have, I can't completely lower my tailgate when I am hooked up to the trailer. Therefor I need to figure out how to close the tailgate. Or I guess I could just scrap my current box cover, and order the diamondback cover.

The rest of the time it's not an issue, as I have a nice little enclosed trailer that the quad will travel in.
